Title: Tandem two-terminal perovskite-silicon multilayer solar cell
Inventor: AŠMONTAS Steponas
IPC: H01L31/00
Filed: 2021-05-28
Abstract: PAGE \* MERGEFORMAT 6SUMMARYTandem two-terminal perovskite-silicon multilayer solar cell The invention relates to the field of solar cells. The proposed tandem solar cell consists of two solar cells, perovskite and crystalline silicon, connected in series, and good contact between them is provided by a semiconductor tunnel junction featuring low electrical and optical losses. The advantage of the proposed perovskite/silicon solar cell is achieved by the fact that it does not need creation of the tunnel junction as a separate additional structure, but the tunnel junction is created by means of appropriate doping of electron transfer layer of the perovskite cell during the fabrication of the layer. Thus, production of the tandem perovskite/silicon solar cell involves fewer technological operations and requires less materials, and the tunnel junction being above the silicon solar cell demonstrates low ohmic resistance within the low-voltage range and does not absorb light photons required to generate electrons and holes in the silicon solar cell.The invention relates to the field of solar cells.

IPC: B21D31/00
Filed: 2021-10-08
Abstract: The invention belongs to the field of processing various sheet materials. More specifically, it is a device for the production of parts from plastic or ductile metal sheet materials by gradual forming. The device can be used to manufacture a limited number of pieces of medical supplies, vehicles, including aircraft, for example, to develop and test a prototype. The device for gradually forming parts of sheet materials comprises a high-frequency oscillation generator, a waveguide with a ferromagnetic spherical tip, which is attached to the end of an annular oscillating waveguide by contact with a permanent magnet. The temperature of the ferromagnetic sphere is regulated through a fibre optic that is passed through the central region of the high frequency oscillation generator and the oscillation waveguide. Thermal energy is supplied by a laser beam by said fibre optic. High-frequency mechanical oscillations are transmitted from a generator controlled by an ultrasonic oscillation controller via a waveguide and a ring-shaped permanent magnet to a ferromagnetic sphere.

Abstract: 949,645. Piezo-magnetic microwave generating apparatus. WESTERN ELECTRIC CO. Inc. Nov. 8, 1961 [Nov. 10, 1960], No. 39934/61. Heading H3B. An arrangement for generating microwaves comprises a magnetically anisotropic gyromagnetic body, ferromagnetic, ferrimagnetic or antiferromagnetic placed in a magnetic field and mechanically pulsed by pressure waves at a supersonic frequency whereby the magnetic field in the body is altered in magnitude or direction to an extent and at a speed to produce continuous gyromagnetic precession, the pulsing period being shorter than the relaxation time of precession in the body and the precession frequency being induced in a conductor for application to a load. The crystal 11, Fig. 1, which may be a sphere of yttrium iron garnet, has directions of easy and of hard magnetization which are interchanged by the pressure waves as described with reference to Fig. 2 (not shown) to move the axis and field strength of the effective flux through values as described with reference to Fig. 3 (not shown). The sphere 11 is mounted on and bonded to a pressure focusing core 19, to the spherical base of which is attached a barium titanate transducer 12 energized by an 8 mc/s. source 17. The relaxation time is said to be 10<SP>-6</SP> seconds. The output loop 22 is tightly coupled to the sphere and the whole apparatus may be included in a conductive shield which could take the form of a resonant cavity and provide coupling means for the generated energy. A resonant cavity arrangement coupled to a waveguide via an iris is described with reference to Fig. 4 (not shown) and in this arrangement the crystal is biased with a static pressure. An arrangement using antiferromagnetic material, e.g. cobalt fluoride and, which does not employ a biasing field and in which the orientation of the material is such that the preferred direction of magnetization is inclined to the direction of the line of pressure is described with reference to Fig. 5 (not shown) and in this arrangement which normally has no net magnetic moment electrons precess in the period following deformation. An external biasing field may be used with this arrangement to produce two resonant frequencies.
